Core Viewpoint - The winter season is significantly delayed in many southern regions of China, with temperatures remaining unusually high, attributed to weak cold air influences and a northward shift in cold air patterns [1][2][4]. Group 1: Weather Patterns - Southern cities like Shanghai, Chongqing, and Hangzhou have not yet officially entered winter, with temperatures exceeding 15°C, which is notably higher than the historical averages for this time of year [2][3]. - Shanghai's average winter onset date is December 5, but this year it is delayed by nearly 20 days, with the latest recorded winter onset being December 25, 2021 [2]. - Hangzhou has also broken its record for the latest winter onset, with temperatures reaching 21.3°C just before the winter solstice [2][3]. Group 2: Meteorological Analysis - The delay in winter is primarily due to the relatively straight mid-latitude westerlies since late November, which hinder the accumulation and southward movement of cold air [4]. - Cold air has been frequent but mainly affects regions north of the Yangtze River, with limited impact on southern areas, leading to a predominance of warmer temperatures [4]. - Data from Shanghai indicates that the prevailing winds have been from the northeast, southeast, and south, suggesting minimal influence from cold air [4]. Group 3: Upcoming Weather Changes - A significant cold front is expected to impact most of China from the night of December 23, leading to temperature drops of 4-6°C, with some areas experiencing drops of over 10°C [6]. - This cold air will likely facilitate the official onset of winter in southern cities like Shanghai and Hangzhou, which are projected to see temperature declines approaching 10°C [6].

Core Viewpoint - A new round of rain and snow weather is expected to develop in China's central and eastern regions, with significant snowfall anticipated in parts of the northeast, necessitating public awareness for travel safety [5]. Weather Conditions - The central meteorological station forecasts that from December 21 to 24, two cold air masses will affect China, leading to fluctuating temperatures across various regions [6]. - Yesterday, significant rain and snow were observed in the southern regions, while snowfall decreased in the north, primarily occurring in Xinjiang and other areas [1]. - Today, snowfall is expected to increase in Xinjiang, while the central and eastern regions will experience less precipitation [1]. Regional Forecasts - Tomorrow, light snow or sleet is expected in areas such as southern Xinjiang, Gansu, northern Shaanxi, and parts of the northeast and northern China, with some regions in southern Xinjiang anticipating moderate to heavy snow [2]. - The day after tomorrow, light to moderate snow or sleet is forecasted for northeastern regions, with heavy snow and local blizzards expected in parts of Heilongjiang, Jilin, and Liaoning [4].
